Your New GoldenEar Speakers
GoldenEar Invisa ® MPX in-ceiling speakers are designed to fit beautifully in a wide variety of applications. Their low-profile grille and nearly invisible design allow for perfect integration in a wide variety of locations within your home. To get the best performance possible and for a product that lasts a lifetime, we strongly recommend that you follow the placement and setup guidelines provided in this manual.

Cleaning
Do not use a strong or abrasive cleaner on your new speakers’ grilles. Clean them only with a damp cloth, but do not get them wet.

**Preventing Speaker Damage

**

USE AN APPROPRIATE AMPLIFIER. At high volumes, a very powerful amplifier can overdrive your speakers and damage them. And if the amplifier is not powerful enough, it can produce distortion that can easily damage your speaker. (Consult your dealer for assistance.)
DON’T BE FOOLED BY YOUR RECEIVER’S VOLUME CONTROL. It only adjusts how loud, it is not an indication of power output. If your speakers begin to sound harsh or grating or if you hear other forms of distortion, turn down the volume immediately!
**** Avoid the use of tone controls and loudness controls as they will demand even more power from an amplifier, lowering the volume at which damage could occur.

GoldenEar Invisa ® MPX speakers are efficient and can be driven to loud listening levels with moderate amplifier power. They are also able to handle the output of very powerful amplifiers. To prevent damage to your speakers, please read all of the following guidelines before hooking them up.

Amplifier Distortion — #1 Threat to your New Speakers!
Amplifier distortion is the principal cause of speaker damage. When listening to loud levels your amplifier may run out of clean power. It will then begin to produce speaker-damaging distorted power. This will damage any brand of the speaker very quickly! More powerful amplifiers are actually safer — For example, A 40 Watt/channel amplifier will have substantial distortion above 40 Watts. If driven to 50 Watts, this amplifier will deliver speaker-damaging distorted power! But a 100 Watt/channel amplifier will have very low distortion below 100 Watts. Therefore, when the speaker requires 50 Watts, this more powerful amplifier will deliver clean power and speaker damage is less likely to occur. (See your GoldenEar dealer for amplifier recommendations.

Volume Setting
Do not be fooled by the Volume setting of your receiver/preamplifier. It only adjusts listening level — it is not a “power-output” dial. The amount of amplifier power actually used at a given Volume setting depends solely on the nature of the source material you are listening to (at a given Volume setting a quiet section of music will use less amplifier power than a loud section). With typical material, the rated output power of many receivers/ amplifiers is often reached when the Volume is set to around -10dB, or between the “11” and “1 o’clock” settings with an analog control (with bass/ treble and loudness controls not used — otherwise rated power may be reached at even lower Volume settings). Remember, all amplifiers produce distortion when operated beyond their rated output power. The resulting distortion will damage all speakers! If you listen to loud levels, be careful to listen for the point of audible distortion — if the speakers begin to sound distressed, turn the volume down, or your speakers and/or amplifier(s) will be damaged! This type of damage constitutes abuse and is not covered by the warranty. If louder volumesaredesired, consider amorepowerfulamplifier.

There is Actually a Limit!

Even with these safer, more powerful amplifiers, there is a point at which you could have more power than the speaker can handle. At that point, you will overpower the speaker and damage it. At loud levels do not increase bass/treble controls from zero and ensure that all loudness/contour/bass EQ buttons are off (otherwise rated output power will be reached at even lower volume control settings).

The Right Amount of Power
A power-range rating is given in the specifications as a guide to indicate the approximate minimum and maximum power input of your GoldenEar Invisa® MPX speakers. Amplifiers that meet or even exceed the speaker’s power range rating are recommended as their greater power reserves provide better sound. But always use the speakers within their power-range rating to prevent damage — that is, keep listening levels below the point of obvious audible distortion.

Speaker Placement
GoldenEar Invisa ® MPX speakers are designed to allow flexible placement while providing a very large window of sound throughout your listening room. Please remember that although the following recommendations are usually valid, all rooms and listening set-ups are somewhat unique. Remember, whatever sounds best to you is correct.

Room Acoustics
GoldenEar Invisa ® MPX speakers are designed to provide exceptional sound in a wide variety of domestic settings. It is important to note however that listening room construction, dimensions, and furnishings all play a part in the quality of sound you will ultimately achieve from your new speakers. The listening room will impose its own character on the performance capabilities of the speaker system. Regarding the room, please note that:

•  Mid and high frequencies are affected by the amount of soft furnishings in your room — curtains, carpets, sofas, wall coverings, etc. An excess of such items can result in a somewhat dull sound. The same room without any soft furnishings can produce an overall bright sound. The typical quantity of soft furnishings found in most living environments provides the right acoustic characteristics to allow the speakers to sound balanced. To help control for these differences, your new Invisa MPX speakers have a high-frequency EQ switch to increase or decrease the HF level to accommodate different room acoustics and placements;
•  Concrete floors and walls tend to aggravate low-frequency standing wave problems;
•  Rooms, where height, width, and length are similar, can exhibit significant low-frequency standing wave problems. This may result in reduced clarity. In such rooms avoid corner placement to minimize acoustic problems.

The extra care you take in correctly positioning the speakers will result in greater listening enjoyment. So, keep the following guidelines in mind when deciding on the best speaker placement.

To ensure the best performance possible, observe the following placement guidelines:

LOCATION: When preparing to install your speakers pick a location that has the required clearance between wall studs or ceiling joists. Make sure to check for wiring, conduit, water pipes, HVAC ducts, and other obstructions before cutting the installation hole.

ACCURATE TIMBRE: For the most accurate and natural timbre, for in-wall music installations, speakers’ high-frequency drivers should be at approximately ear level. Stereo pairs should be placed an approximately equal distance apart. Select locations that allow the sound to reach the listening area unobstructed by furnishings.

BALANCED BASS: Placing speakers in corners will over-emphasize bass and reduce overall clarity. If possible, position speakers away from either sidewall. This will ensure better bass performance and optimal midrange clarity.

FOR BEST IMAGING: For in-wall installations of L/R mains, measure the distance from your main listening area to the left front speaker (we’ll call this distance “X”). For optimal imaging and largest soundstage, place speakers “X” distance apart from each other (and no less than 3 /4 of that distance — 3 /4 of “X” up to “X”). For Home Theater installations with L/C/R in-walls, place the center speaker above or below your TV, whichever position is closer to ear level, as shown in the figure below:

Positioning Invisa ® MPXs as Left/Right/Center Fronts

Positioning Invisa ® as Surrounds/Rears

When used as surround speakers in a 5.1 system, Invisa ® speakers may be located on the side, above, or behind the listeners. When used on the sides, take care never to locate the speakers forward of the listeners (A). If the speakers are placed along the rear wall as surrounds, it is suggested that they be positioned fairly wide apart if possible, in-ceilings in the corners are also a good location. For instance, if there is a couch in the center of the rear wall on which the listeners will sit, try to position the speakers wider apart than the couch (B). Rear speakers in a 7.1 system should be placed fairly close together (4-6 feet) as shown (C). Surround and rear speakers should always be positioned as high as possible in the room.

Speaker Break-in
Your new Invisa ® MPX loudspeaker system should sound good as soon as you turn them on; however, an extended break-in period of 40-60 hours or more of normal playing time is required to reach full audiophile performance capability. Break-in allows the driver suspensions to work in and crossover components to “heal,” resulting in fuller and tighter bass, a more open “blossoming” midrange, and smoother high-frequency reproduction

Color-Match Painting (optional)

Your new Invisa ® MPX speakers include a paintable “edgeless” grille that completely covers the installed speaker. The grille comes in a neutral white to blend with most areas, however, for the ultimate in “stealth” installation, they may be painted to match any decor. PLEASE NOTE: Failure to follow the instructions below may result in serious degradation of sound quality!

Please Note:

• Do not paint the grille with a brush or roller — this will clog the grille’s acoustic perforations and muffle the sound.
• It is not necessary to remove the backing cloth, or scrim, from the grille before painting.
• Do not heat cure the finish.
• Do not paint the grilles while attached to the speaker.

To paint, follow these steps:

1. Remove the grille from the speaker and place it on a drop cloth

2. Spray paint the grille using:
   i. A spray paint that closely matches the color and shines desired.
   ii. A custom-made spray can be color-matched to your paint finish.
   iii. The indoor latex paint used to paint the ceiling or wall but diluted to the paint manufacturer’s/ spray gun manufacturer’s recommendations

3. In a well-ventilated area, apply several light coats of paint, sprayed at about a 60-degree angle from the grille’s surface, letting the grille dry completely between coats. Follow the paint manufacturer’s directions.

4. To ensure the paint is evenly applied, each coat should be applied from multiple directions (at least four).

5. Once the painted grille has dried completely, if necessary you can use a brush or small roller to touch up the grille’s outer edge — just be careful not to get any additional paint on the grille’s perforated surface.

Installation Instructions

Installation of your new Invisa ® MPX speakers requires the use of tools such as a drill, screwdriver, saws, and possibly other power tools. The installer should have knowledge of all applicable building and/or fire codes. Care must be taken to ensure the area behind the wall or ceiling where you plan to install the speakers is clear of obstructions. When
cutting the hole in and running wires through walls and/or ceilings proper care must be taken to avoid electrical, water, gas, and/or HVAC pipes and the corresponding risks to your safety and risk of damage to property.

If you are not comfortable with the above and/or performing the following installation procedures we strongly suggest having a professional contractor install your speakers (see your GoldenEar Dealer).

Tools Required:

• Pencil
• Drywall saw, Keyhole saw, utility knife, or another material-appropriate cutting tool for wall material
•  Phillips Head Screwdriver
•  Power drill with an appropriate bit (optional, for starting wall cut

Installation Into Existing Walls or Ceilings

For new construction (pre-drywall), use our custom rough-in brackets, sold separately. Use the only cable that is rated for in-wall use (UL Standard CL2, CL3, and CM, CSA standard FT4).

1. Make sure the wall material can support the weight of the speakers you plan to install (see specifications page for weights).

2. Make sure the location selected is free of studs, electrical wiring, water or gas pipes, etc. Prior to installing, hold the speaker in your selected location to make sure it is clear
   of any obstacles. PLEASE NOTE: Your cutout must be at least 2″ (50mm) from adjoining walls/ceiling, internal studs, and any pipes.
   

3. Place the included mounting template onto the wall or ceiling in your preferred location. Use the pencil to trace around the template (Figure 1).

4. Carefully cut a hole with the appropriate cutting tool along the pencil trace as follows: Start the hole by drilling a hole inside of the pencil line (place drill bit just inside the line). Use this hole to insert the cutting tool and begin cutting — be careful not to cut outside the template line! (Figure 2).
   

5. For In-Wall Mounting:
   • For optimum performance, loosely place two pieces of standard fiberglass insulation in the wall, one just above the hole and one just below. An 8″ x 10″ piece should work well, R-12 for a 2×4 wall, R-20 for a 2×6 wall.
   •  Also, place a half-think piece of fiberglass insulation cut to the height of the speaker in the wall right behind the mounting hole.
   Turn your amplifier/receiver OFF before performing any connection steps, in order to prevent accidental damage to your amplifier.
   If you plan to use multiple speakers per amplifier channel. The minimum impedance of ONE Invisa in-wall/in-ceiling speaker is 4 ohms per channel.

6. Pull the speaker wire out of the hole and connect the speaker as follows:• Your Invisa ® MPX speakers are equipped with a set of high-quality push spring connectors that can be used with bare wire. Make sure all wires are firmly fastened. Always use a high-quality speaker wire of the correct rating (see above) and a sufficient gauge for the distances you are running (see your dealer for assistance).
   •  Strip 1 /2″ (12 mm) of insulation from each of the two conductors to expose the metal, twist the strands of each into a single un-frayed strand.
   •  Hold the speaker up to the cutout and connect the speaker cable. Proper polarity (or phase) is critical for proper stereo imaging and bass performance. Connect the red(+) terminal of your receiver or amplifier to the red(+) terminal of the Invisa loudspeaker and the black(-) terminal of your receiver or amplifier to the black(-) terminal of the Invisa loudspeaker (See Figure 3). Most speaker cables are either color-coded or have some indicator (ribbing or writing) on one of the conductors to help maintain this consistent polarity. It is essential that all speakers be connected in the same way (in- phase) to their own channel of the amplifier. If you experience a great lack of bass, it is likely that one speaker is out of phase (+ and – reversed) with the other.
   •  Push down on the top of the speaker’s push terminal to reveal the wire hole in the post. Insert the wire into the hole and release your pressure on the terminal.

7. Loosen the six rotating lock arms on the speaker by turning the arm screws on the front of the speaker counterclockwise 1/2 to 1 turn, just enough to allow the lock arm to move freely (Figure 4).
   • Make sure the rotating lock arms are positioned inwards (Figure 5) so that your speaker fits into your cutout hole.

8. Holding the speaker’s front lip with your thumbs and index fingers, carefully slip the speaker into the cutout and hold it firmly in place. (Figure 6).

9. While holding in place, tighten the six lock arm screws with a screwdriver (Figure 7). This will rotate the lock arms and secure the speaker to the wall/ceiling. DO NOT OVERTIGHTEN the lock arm screws as this could damage the drywall. If you are using a power screwdriver or drill, set the torque to a value of no more than 7 in.-lb (8dN-M )

10. Install the grille by placing it over the installed speaker and aligning the powerful miniature magnets.

Setting the Invisa Speaker’s High-Frequency EQ Control (HF EQ Switch)

We suggest starting with the HF EQ control (Figure 8) in the center position, in typical rooms with a balance of reflecting and absorbing surfaces. If, however, your listening room is overly “bright” due to many reflective, hard surfaces, select the “-” position to effectively compensate for this type of room acoustics issue. If, however, your listening room is filled with heavy furniture and fabrics or you are sitting fairly far from the speakers, making the sound “dull”, select the “+” position to compensate for this type of room acoustics issue.

Setting Bass and Treble Controls on Receiver or Amplifier
Normally we recommend that you set the “Bass” and “Treble” controls on flat (or off, or 0 dB). The same applies to a graphic equalizer; we recommend that you leave it flat (or off). This will give you the most accurate and natural sound. If you want more bass, raise your subwoofer’s “Level” control (or raise the subwoofer level on you’re a/v receiver), keeping in mind that even a little turn of the knob can make a big difference in the sound. The reason for this recommendation is that we have discovered what is often thought to be improper sounding speakers is, in fact, a problem caused by the use of tone controls. When in doubt, leave them out (flat); this almost always results in the best possible and most natural-sounding system performance.

Complete Home Theater Systems
We strongly suggest that you use matching GoldenEar Invisa ® loudspeakers and a ForceField ™ subwoofer, for your complete GoldenEar home theater system. Invisa ® MPX speakers are designed to be used as front, rear, and/or side surround speakers, with exceptional results for both music and movies. Of particular note, the GoldenEar ForceField Subs have been designed specifically to make a perfect match with the Invisa ® MPX speakers.

Using the Invisa ® MPX in a Multi-Channel Home Theater Application
When using the Invisa ® MPX as part of a home theater system that includes powered subwoofer(s), it is extremely important that bass is directed to the subwoofer and NOT the Invisa ® MPX speakers. This is done through the use of a high-pass filter, implemented as part of the setup of the bass management system of your home theater receiver/processor (see below).

Setting Channel Levels and Bass Management
Multi-channel surround sound systems have bass management systems (systems that direct the bass to the various channels) which vary from unit to unit. This bass management system must be properly adjusted, in particular, it is extremely important that bass is directed to the subwoofer and NOT the Invisa ® speakers in these setups, through the use of bass management settings as described below. Many problems relating to the overall sound of the system can be traced back to improper bass management. Also, note that Multi-channel surround sound systems have a critical channel balancing procedure for setting the level for all speakers which must be followed if the system is to perform properly. Many problems relating to the overall sound of the system can be clearly traced back to improper system balance.

Home Theater System Bass Management Settings: On your Home Theater receiver or A/V processor’s Speaker Setup Menu, set speaker to “Small” for all channels using Invisa ® MPX speakers, and set Subwoofer to “Yes.” The standard 80Hz crossover is the recommended setting (or at least starting point) for the crossover setting.

Setting Channel Levels: On your receiver or A/V processor’s Speaker Level Calibration Menu, set each speaker (channel) in the system to the same volume level. While you can get reasonable results doing this by ear, it is best to use an inexpensive Sound Pressure (SPL) meter to get a better channel-to- channel balance. Some new receivers and processors have Auto Set Up functions that use a supplied microphone to set levels automatically.

Troubleshooting

If you experience any diffi culties with your Invisa ® MPX speakers, try the suggestions described below. If you are still having problems, please consult your GoldenEar Authorized Dealer for assistance.

1. Make sure all your system interconnects, speaker cables and power cords are solidly in place.
2. Check that no foreign objects or liquid have entered the speaker.
3. If no sound comes out or the sound is distorted in some way and you are sure the system is set up properly, please bring the speaker to your GoldenEar Authorized Dealer for assistance. But make sure you call fi first.
